Reinstall Win 10 upgrade after HD reformat
The original OS on my PC was Win 7 Pro. I upgraded to Win 10-Pro a while ago with the free upgrade path. I was having trouble with the PC running very slowly and was told by the manufacturer that it was probably because the HD was dying. I don't think it is, but to give the PC its best chance I decided start out afresh, so reinstalled Win7 from the original CD supplied, spent 2 days with Windows update to get Win 7 'up to date' and updated all the drivers I could. and then tried to upgrade again. Unfortunately it now asks for the product key. I used the original Win 7 product key (worked last time) but this now no longer works. I tried using the Win 10 product key that I got off a Belarc Advisor report I ran before reformatting the HD. That doesn't work either. I know this is well past the deadline for upgrade, though I upgraded a couple of other PCs about 3 months ago without difficulty. Any suggestions on what I can do?
Also I have errors showing in Device Manager saying driver not installed for SM Bus Controller and USB Controller. The PC has both USB 2 and USB 3 ports. The USB 2 work but the USB 3 have stopped working.
PC is quite old (2012) but still working reasonably. The Win 7 reinstall has dealt with the speed issue I had previously.
Thanks
